CRITICAL UPDATE: This release fixes requirements to exclude pymodbus version 3.8.0 and higher. Everyone must apply this update.
The requirements were incorrectly set without an upper version limit. Pymodbus 3.8.0 introduces breaking API changes that are not backwards compatible. Without an upper limit in the requirements file, HA will download the latest version of pymodbus which will cause a failure the next time you restart or upgrade Home Assistant. This integration has been tested with pymodbus 3.6.6 through 3.7.4.
If you are using a v2.x.x release please read the release notes for v3.0.0 before updating.
